ORGAN.

srncrmce'rron forming part of Letters Patent No. 713,084, dated November 11, 1902.

Application filed July 22, 1899. Renewed September 26, 1902. Serial No. 124,954. (No model.)

aZZ whom it may concern.

Be it known that I, HENRY O. FLETCHER, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Organs, of which the following is a specification.

My object in this invention is to reduce the n umber of pipes in pipe-organs,thereby economizing the amount of room needed for the instrument and also reducing the cost of production. I accomplish this object by making the individual pipes capable of producing two or more tones varying from each other either in power,quality, pitch,or kind and controlled from separate registers and forming stops which maybe used simultaneously, but are as independent of each other as though separate sets of pipes were used. The pipes are adapted to this double use by providing them with a plurality of months or other sound means,each havingits own independent windway connecting it to the wind-supply and forming one note of a stop separate from the stop or stops to which the other sound'producing means and windways embodied in thesame pipe belong.

The nature of the invention will be fully understood from the description given below and from the accompanying drawings, in which I show at- Figures 1 and 2 elevations of the opposite sides of a pipe embodying my invention, and at Fig. 3 a partial elevation of a third side thereof. Fig. 4 is a partial Vertical section. Fig. 5 is a section on the line 5 5 of Fig. 3, and Fig. 6 is a plan of the wind-chest.

In said drawings, A represents a flue-pipe of an organ, which, except in respects hereinafter pointed out, is of the ordinary construction. It is provided with the mouth 13, the block A, a foot A, containing the windway and connecting the passage or chamber A below the block with a corresponding windpassage E of one of the registers of the organ. At one of the other sides of the pipe is another mouth 0, belonging to a different stop from the mouth B and producing a tone of the same pitch as that of the mouth 13, but varying therefrom in power. This mouth 0 is connected to the foot-windway B by the air-passage B whichmay be formed mainly,

if not wholly, in the cap 13 attached to the side of the body of the pipe, and deliver its charge of wind to the mouth C, which is an outside instead of an inside orifice, as in the case of mouth B. These parts are also of the usual construction, except that they are our bodied in the same pipe with other soundproducing means. The foot B connects the mouth 0 with the wind-passage F of a diti'erent register from that of passage E.

I have found that a pipe constructed as set forth and embodying separate mouths and windways for the same note in dififerent stops may be advantageously used, as it greatly economizes room and cost by reducing the number of pipes, especially in the case of large sizes.

By the construction thus far described a single pipe is adapted to produce two tones of analogous character,but differing in strength. I may, however, provide it with mouths other than those shown or with reeds 'or other sound-producing means adapted to produce tones varying in quality, pitch, or kind, and hence do not wish to be limited to pipes producing tones differing only in respect to their strength, nor to pipes producing only two varying tones. I show in the drawings a third sound-producing deviceto wit, a reed D inclosed in a boot D, having an eschalot D" and a tuning-wire D The eschalot registers with the upward air-passage D communicating with the resonator-chamber of the pipe. This reed may be tuned either in unison with the fundamental tone of the pipe or to any harmonic thereof. The boot D 0011 nects with the wind-channel G of the register in which the reed is embraced. The windchannels E, F, and G of the dilferent registers may be embodied in a single wind-chest E, as shown at Fig. 6.

\Vhile I have shown only a single pipe and its connections in the drawings, it will be understood that the invention may be used in a large proportion of the pipes usually embodied in pipe-organs, both wood and metal.

I claim- 1. The organ-pipe having a plurality of sound-producing means belonging to (litterent registers,and a separate windway for each connecting them to the wind-channels of the registers, substantially as specified.

2. The organ-pipe having a plurality of sound-producing means belonging to different registers and adapted to be sounded simultaneously, and a separate windway for each connecting them to the Wind-channels of the registers, substantially as specified.

3. The organ-pipe having a plurality of mouths and windways connected to the windchannels of different registers, and giving out similar tones varying from each other in strength, substantially as specified.

4. The combination of separate registers with a single pipe having independent wind- Ways connecting it to the Wind-channels of the registers, and also having a separate I 5 sound-producing device connected with each windway, substantially as specified.
